semic.es website review

61 files are served with short cache lifetimes, so returning visitors download them again (28.9 MB).

49 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.5 s.

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

About 74 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 330 ms faster on a phone.

1 image could be 26 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

About 70 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 third-party services load with your homepage (JSDelivr CDN and Cloudflare CDN), adding 68 KiB and 26 ms of main-thread time.

11 KiB could be saved by minifying CSS.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Visually, the page fills in at 17.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Asegura hoy la tecnología del mañana”. Most of its time is element render delay (11.1 s).

The page becomes fully interactive after 3.9 s. Good is under 3.8 s.

1 image have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 29.0 MB in 77 requests on a phone: media 28.6 MB (7), scripts 165 KiB (11) and stylesheets 121 KiB (45). Under 2 MB keeps phones on slow connections fast.

sostenibilidad_home_10_25.jpg weighs 1.2 MB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example sostenibilidad_home_10_25.jpg at 2,000 px wide, shown at 390 px. Resized copies would save about 823 KiB.

1 image (1.2 MB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

logos_banner_0.png.avif is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 8.21 g of CO₂e: 984.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

2 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

11 visible links have no text or label, so screen readers cannot say where they go.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 125 pages on semic.es and 26 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://econocom.semic.es/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/ and https://econocom.semic.es/es all use the title “Econocom|Semic - Tu proveedor global de soluciones y servicios IT”. Search engines can't tell which page to show for a search, so each competes with the others.

https://econocom.semic.es/es/quienes-somos/alianzas has no meta description, so Google writes the search snippet from whatever text it finds.

https://econocom.semic.es/es has no <h1> headline, so visitors and search engines get no clear main topic.

https://econocom.semic.es/es/quienes-somos/etica-y-cumplimiento, https://econocom.semic.es/es/que-hacemos/workplace, https://econocom.semic.es/es/que-hacemos/infraestructura and https://econocom.semic.es/es/que-hacemos/audiovisuales took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 41 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 753 words of visible text.

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
